87.5 grams per 75 mL = 87.5/75 grams per mL = 1.1666... grams per mL
d = m/v, so the density is 1.5 g/mL
density = mass/volume → The density of the rock is the mass of the rock divided by the difference in the volume from before the rock was dropped in and afterwards. Its units are grams/ml
By definition, it weighs 50 grams. A litre of water weighs a kilogram.
If 50ml = 52g 100ml = 104g 1ml = 1cm3 104/100 = 1.04g/cm3
50 grams
Place the piece of metal in 50mL of water and subtract the 50mL from the new volume of water. The difference will be the volume of the metal in mL and cm3. Then find the density by dividing the mass by the volume of the metal. The water must completely cover the metal in order for the displacement method of determining the volume to work.
specific gravity of 4 4 times the mass of water, which at 50ml would weigh 50 grams.
Density = Mass/Volume = 150g/50mL = 3 grams per millilitre.
The object has a density of 20 g/mL
density = mass/volume → The density of the rock is the mass of the rock divided by the difference in the volume from before the rock was dropped in and afterwards. Its units are grams/ml
To calculate the density, you need to divide the mass by the volume.
By definition, it weighs 50 grams. A litre of water weighs a kilogram.
Oil
You will need to expand on your questions 50g of what - lead, oil, mercury, water???? You divide the mass by the density (in common units) to get the volume then convert to the required units. i.e. for cold water density = 1000 kg/m^3 50g = 0.05kg 1m^3 = 1000 Litres = 1000000 ml. so 0.05 / 1000 * 1000000 = 0.05 * 1000 = 50ml. or another way to remember this is 1 litre of water = 1kg therefore 0.05kg water = 0.05Litres
20,000 50ml is a measure of volume. 1 ton is a measure of mass. Your question can only be answered once you specify the density of the matter that occupies the 50ml of volume. There was no mention of water being the matter in question.
If 50ml = 52g 100ml = 104g 1ml = 1cm3 104/100 = 1.04g/cm3
The liquid's density is 0.8 g/mL
Assuming the density of water is 1 g/mL, the mass of the water bottle would be 700 grams. If the density is different, you would need to know the specific density of the material the water bottle is made of to calculate its mass.
